Spirit-filled Rockets
There is a really awesome science experiment involving making film canister rockets in the book "Beakers, Bubbles & the Bible: Bible Lessons from the Science Lab" by Tina Houser.
ISBN 978-1-59317-329-6
It is scriptural based, and a lot of fun for the kids, who get to launch rockets made of film canisters and Alka-Seltzer! I highly recommend the book, as the index that lists all 58 science experiments by scripture reference, and the Table of Contents lists each topic. Great reference for Children's ministry!
